My thinking has been modoki, but perhaps raindance has other ideas...obviously its wide open, at this point. The fact that its beginning as east based does nothing for me in terms of significance.
I will say, though, that guidance last fall in terms of evolution with regard to placement of greatest SST anomalies was piss poor...I think only the Canadien had it shifting into a modoki. Kudos to raindance for picking up on that because I did not.
